PoE Injector Grandstream GS-POE15W-MG, 15W Power over Ethernet (Ethernet injector)

The Grandstream GS-POE15W-MG is a 15W Power over Ethernet injector designed to deliver both power and network connectivity to compatible devices over a single Ethernet cable. Compact and easy to install, this Ethernet injector is intended for use where PoE-capable switches are not available or when individual devices such as IP phones, wireless access points, or compact network cameras need a localized power source. The unit connects to a separate AC power input and injects PoE on the Ethernet output port while passing data from the Ethernet input.

Advantages

The injector provides a straightforward solution for adding PoE capability without changing existing network switches. Its compact footprint and simple two-port configuration reduce installation complexity and allow flexible device placement. The device supports standard PoE power delivery up to 15W, ensuring compatibility with a wide range of low-power endpoints. Passive operation requires minimal configuration and is suitable for deployments that need a reliable single-device power source for Ethernet endpoints.

Suitable for

• Supplying power to IP phones that require up to 15W
• Powering small wireless access points and range extenders
• Providing power to compact PoE-enabled surveillance cameras
• Enabling network devices in locations without PoE switches
• Temporary deployments and lab/testing environments

Key specifications

• PoE power output: up to 15 watts
• Ports: separate Ethernet input (data) and PoE Ethernet output (data + power)
• Power input: external AC adapter required
• Form factor: compact inline injector design
• Compatibility: IEEE/industry-standard PoE for 15W-class endpoints

How to use

Connect the injector's Ethernet input port to a network switch or router using a standard Ethernet cable. Attach the network device that requires PoE to the injector's PoE output port with another Ethernet cable. Plug the external AC adapter into the injector and then into a mains outlet. The injector will supply power and pass data to the connected device; no additional software configuration is typically required. Verify that the powered device supports PoE and does not exceed the 15W power budget.

Usage recommendations

Use the injector with devices specified for 15W PoE to avoid power shortages. Place the injector near networking equipment or accessible power outlets to ensure secure cabling. For deployments with multiple PoE devices, consider a PoE switch with adequate power budget. Regularly inspect cables and connections to maintain reliable power delivery and network performance.
